PUTTYLESS WINDOW-SASH.

Specification of Letters 'Patent Patented Sept. 13, 1910 Applicationfiled May 22, 1909. Serial No. 497,633.

To all whom it may concern:

Be it known that I, ROBERT FRTEDEL, a subject of the Emperor of Germany,residingl at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in PuttylessWindow-Sashes, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to improvements in puttyless windowsashes and hasfor its object to provide simple and effective means whereby a windowpane, sky-light, or other kind of glass can be securely and safely heldin position.

Othenobjects` and advantages of my invention will appear in the courseof the followingspecifieation.

In the accompanying drawing: Figure 1 is a horizontal sectional viewtaken through a double window sash fitted with my improved window panesecuring means; Fig. 2

is a front view of one of the securing means and, Fig. 3 is aperspective view of one of the securing strips employed to hold thewindow pane in position.

Referring' to the drawing, which illustrates the preferred form of myinvention, l,

designates a double window sash of ordinary construction, which is heldin position in a frame 2 by means of the usual cleats or beads 3 and 3a.The window panes 4 and 4a respectively are similarly held in position,so that a description of the manner in which one of them is secured inplace will answer for both.

The window sash is suitably rabbeted on the inside, as at 5, and thisrabbeted portion is provided on its outer edge with a beveled, orslanting, groove 6. Suitably secured in the groove 6 by meansofwater-proof glue is a semi-cylindrical piece of rubber tubing, 7, orother suitable material. The semicylindrical piece of material 7, itwill be notedis secured in position with its outer edge 7a projectingslightly outside of the groove 6, for, a purpose to be hereinafterexplained.

In order to hold the window pane in position securing strips 8 areemployed. 'Ihese securing strips are provided on their outer edges withbeveled, or slanting, grooves, 9, similar to the groove in the rabbetedportion 5, and in these grooves are secured semieylindrical pieces oftubing of rubber, 7, or other suitable material by means of a waterproofglue. These pieces of tubiner 7 are so secured in the grooves 9 thattheir outer sides project slightly beyond the outer edge of the grooves,as at Dn. The securing strips 8 are secured in position by suitablefastening means 10.

As is clearly shown in the drawing, the grooves 6 and 9 mate, so thatwhile the inner edges of the strips of tubing 7 carried by each groovecontact, the outer edges project slightly beyond the outside of therabbeted portion andthe securing strips 8, and thus it will be seen thatthe window pane 4 is held firmly by the rubber tubing 7, or othersuitable material, and, hence, the window pane does not Contact with anyhard material.

A feature of great importance in my in-- vention is that of having theedges of the semi-cylindrical tubing 7 project beyond the outer edges ofthe rabbeted portion and the securing strips as at 7 and 9, for as aresult thereof water is elfectnally prevented from entering the groovesand injuring the surrounding wood work, or other material of which thesash and .securing strips are made. I, preferably, form thesemi-cylindrical, or curved pieces of material 7 by slittinghorizontally pieces of tubing of the desired size, that is, when a heavywindow is to be placed in position, it will be desirable to employheavier strips 7, than when a small piece of glassis to be secured.

What I claim is:

In a window sash, a frame having a rabbct formed around the inner sideof the opening, said rabbet having a groove extending around its angularedge adjacent to the opening, glass retaining strips adapted to besecured in the rabbeted portion of the frame and each having a groovecorresponding in shape to the first mentionedgroove and located in theinner angle of the respective strips, each of said grooves being curvedin cross section and of the same dimensions, said stripsv having theiredges abutting against the shoulder formed by the rabbet of the framewhen assembled and the grooves in the frame and strips being arranged toform a U-shaped groove ex- I l tending arouni theopenin when the sash Intestimony whereof I hereunto afx mry is xssembid, sections (ut ngthwisefrom; signature in presence' of two Witnesses. ru ber tu Aing cemento int e Orooves o f the frame, and other sectionsL1 similarly ROBER'lFRIEDEL 5 formed from rubber tubing cernented in the v Witnesses: g,
